MX480 PIC Description
PICs provide the physical connection to various network media types, receiving incoming
packets from the network and transmitting outgoing packets to the network. During this
process, each PIC performs framing and line-speed signaling for its media type. Before
transmitting outgoing data packets, the PICs encapsulate the packets received from the
FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the
media type of that PIC.
PICs are hot-removable and hot-insertable. Up to two PICs can be installed in the slots
in each FPC. Up to three FPCs can be installed in an MX480 router. PICs used in a Type
2 FPC have captive screws at their upper and lower corners. PICs used in a Type 3 FPC
have an upper ejector handle and a lower captive screw.

MX480 PIC Port and Interface Numbering
Each port on a PIC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (-) separates the media type from the FPC
number (represented as an FPC in the CLI). The FPC slot number corresponds to the first
number in the interface. The second number in the interface corresponds to the PIC
number. The last number in the interface matches the port number on the PIC. Slashes
(/) separate the FPC number from the PIC number and port number:
type-fpc/pic/port
•
type—Media type, which identifies the network device. For example:
•
ge—Gigabit Ethernet interface
•
so—SONET/SDH interface
•
xe—10-Gigabit Ethernet interface
For a complete list of media types, see Interface Naming Overview.
•
fpc—Lowest slot number in which the FPC is installed. On the MX480 router, FPCs
occupy two line card slots and are represented in the CLI as FPC 0 through FPC 4.
•
pic—PIC number, 0 or 1 depending on the FPC slot.
